Ultrasonic level sensor

Gems Sensors & Controls has launched the UCL-520 ultrasonic level sensor. The UCL-520 Series is suitable for non-contact applications such as industrial water treatment, wastewater management, chemical and petroleum distillates storage as well as many other challenging fluid applications.

The UCL-520 is a 2-wire, 4-20 mA output ultrasonic level transmitter for measurement up to 8 m and is built with a rugged PVDF transducer for challenging ultra pure, dirty coating, scaling, corrosive or waste liquids. The highly accurate sensor is easy to install within limited space applications and the minimum 200 mm dead band allows for maximum fill of media. The UCL-520 offers a 76 mm minimum beam width for restricted space applications and the selectable display indicates level in air gap or liquid height.

The UCL-520 is push-button calibrated with a 6-segment LCD display. The user interface is fast and simple via a scrolling single-layer menu.

The indicator has a stated accuracy of ±0.2% of span in air. Tank fitting is via a 2" NPT threaded connection and the enclosure is IP65 rated.
